Breath of the Black Prince
To go along with the new The Black Prince faction there are some quests that end with the reward of a legendary item, the Breath of the Black Prince! This item is likely used to upgrade your gear in some way. Before helping Wrathion, you first share a drink with him while talking about the future of Azeroth.

The first quest in the series requires an honored reputation level, which is earned by killing the mogu and mantid in the Townlong Steppes and the Dread Wastes, as well as any raid creatures.

At some point after this he will reward you with a Breath of the Black Prince, but the quests are not chained yet, so we can't be certain as to what the requirements are.

According to the quest descriptions he seems heavily invested in the fate of Pandaria, even hinting towards the oncoming Horde and Alliance war fleets that will turn the beach of Krasarang Wilds into a battlezone in Patch 5.1.

Bonus Level-90 Arena Pass Realm

In addition to granting access to the exclusive level-85 Arena Pass realm, players will also gain access to the special level-90 competition when the realm reopens a few weeks after Mists of Pandaria launches. This means that Arena Pass subscribers who have purchased the expansion will be able to access level-90 gear and talents, and be able to take a level-90 monk into the Arena with top level gear.

Players who purchase an Arena Pass and participate in the competition can earn an Armored Murloc in-game pet. The top players will also contend for a chance to achieve the “Vanquisher” title for their live characters.
If you would like to demonstrate your Arena prowess, are eager for a chance to earn exclusive loot, or just want to reserve a spot in the level-90 Mists of Pandaria Arena Pass realm, the time to register is now!

They have only killed the Skeleton King at this point. Do note that up to the Skeleton king is only part of the first act and they still have lots of the game to go till they complete act 1.

Another point to be made is that this is a group of fully co-ordinated, skilled, dedicated and hardcore gamers who have been playing regularly since the moment of release. It will take quite a while longer for the average player and even most seasoned gamers to reach this point. That being said, it's amazing to see the speed in which they have reached this stage of the game, but remember that the hardest is yet to come...

Meh, I prefer to take my time, soak up the atmosphere, listen to the story, and loot every single damn barrel I find.

But yeah, as others here have said, completing normal mode is by no means finishing the game... It's just the start. (Blue Tracker / Official Forums)

Diablo 3 Beaten in 6 HoursThat's the problem... people are used to playing Skyrim
You can beat Skyrim in a few hours if your intent is to rush to the end of the game as fast as possible. You can beat the original Super Mario Bros in 5 minutes.

If your intent is to simply race to the end of the game as quickly as possible I'm sure you can complete Normal difficulty in very little time. If your intent is to take your time and enjoy it, stop worrying about what people rushing to the end of the game think.

Luckily, unlike other games, regardless of how quickly you want to rush to the end, the near-limitless content provided through randomized events, dungeons, enemies and items (and their random drop chance) mean that you'll be able to play for years to come. Welcome to Diablo III, please enjoy. (Blue Tracker / Official Forums)

wonder if they given him(wrathion) a unique dragon welp form now, he did fly away as a normal black welp,end quest wich showed how rushed the quest chain was at the end, plz let it be the ravenholt faction reworked, so rogues wont be forgotten this expansion untill the last raid patch as usual

i just don't get people sometimes. ok, you buy this game you've been waiting for for however many years and then you blast through it, skipping everything it's possible to skip and bitch that it's too short. whaaaat? do these people buy a movie and fast forward to the middle, watch 5 min, then go to the end and complain it was a short movie.

...and then there are the people that stopped playing WoW after vanilla and come to MMO champ and bitch about how they hate MoP. You know who you are...

anyway, was never a big Diablo fan, but I got it w/ my annual pass and it's been pretty cool so far.
